|
摘要
钢管混凝土边框组合剪力墙及筒体是一种新型抗侧力部件。该文对不同混凝土强度等级,不同轴压比,不同剪跨比,不同强弱抗剪连接键等设计参数的矩形钢管混凝土边框组合剪力墙的抗震性能进行了研究。进行了2个普通钢筋混凝土剪力墙和7个矩形钢管混凝土边框组合剪力墙的低周反复荷载试验,以及2个设置不同形式抗剪连接键的剪力墙节点的低周反复荷载试验。在试验基础上,对比分析了剪力墙的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及破坏特征。建立了组合剪力墙的承载力计算模型,计算结果与实测结果符合较好。研究表明:这种新型组合剪力墙及筒体可有效地将混凝土剪力墙侧向刚度和承载力大的优势与钢管混凝土柱抗震延性好的优势组合,钢管混凝土边框柱与混凝土剪力墙之间的抗剪连接键能可靠工作。工程应用效果良好。
Composite shear walls and core walls with concrete filled steeltube columns are new types of members of structures to resist horizontal loads. Aseismic behaviors of composite shear walls with rectangular concrete filled steeltube columns are investigated, considering different design parameters including various concrete strength, axial-load ratio, shear-span ratio and strong or weak shear constructional measures. The experiment of 2 traditional reinforced concrete shear walls, 7 composite shear walls with rectangular concrete filled steeltube columns and 2 joint models with different shear constructional measures have been accomplished by applying low cyclic loads. Based on the experiment, the load-carrying capacity, ductility, stiffness anddegradation, hysteretic property, energy dissipation and failure phenomena of each shear wall are contrastively analyzed. The formulas of load-carrying capacity are established. The results obtained from the formulas are in good agreement with those from the experiment. The results show that this kind of shear walls and core walls can fully play advantages of strong lateral stiffness of concrete shear walls and good aseismic behavior of concrete filled steeltube columns. Shear constructional measures combining concrete filled steeltube columns and concrete shear wall work well. This kind of shear wall and core walls are well applied in engineering.
